Scope, as a sort of Wave-extent, is more the kind of vibrations I have in mind re spectrum – seemingly wrongly..

Perhaps even more so, the german word spähen “to spy”. Sense of “distance the mind can reach..”
This sounds to me more like an innate searchness of a wave.. As in wave as a spy/searching-rhythms that seem to have aim via aimless other energies.. They are just linked, not aimed.. Hence full of energy..? (not power.. power requires aim/meaning..)
